  • The development of eggs and larvae, and minute tubercles on the skin surface of the larvae in Acheilognathus lanceolatus (=Acheilognathus intermedia intermedia) from Korea were observed. The ripe eggs of A. lanceolatus from Korea were nearly spindly. The shape was distinguishable from that of Japan. And then the embryonic development of this specimen from Korea was faster than that from Japan. As regards larval development and morphology and distribution of the minute tubercles, however, A. lanceolatus in both Korea and Japan were same except for the mentioned above two characters. These findings suggested that the two formes should be separated at subspecies level.

  • Twelve species in five genera of parasitic copepods are recorded from seventeen species of freshwater fishes of Korea. They are Ergasilus coniformis n. sp., Ergasilus ventriosus n. sp., E. briani Markewitsch, E. peregrinus Heller, Neoergasilus joponicus (Harada) N. lonsispinosus Yin, N. inflatus Yin, N. bullatus n. sp., N. angustus n. sp., Sinergasilus undulatus (Markewitsch), Lernaea cyprinacea L., and Lamproglena chinensis $Y{\"{u}}.$ As the most prevalent parasitic copepod, Neoergasilus japonicus is found to parasitize as many as ten species of freshwater fishes in Korea. The fish Zacco platypus, from which seven species of parasitic copepods are discovered, turned out to be the most preferred host of the parasitic copepods in this country. Full descriptions are given of the new species and new records of Korea. Lamproglena chinensis, an incompletely known species, is also redescribed.ibed.

  • A new species of gobiid fish Acentrogobius pellidebilis is described from specimens collected in the southern and western coasts of Korea. The new species is distinguished from its apparant sister species, A. pflaumi, by 7~8 predorsal scales and the 5 darker blotches arranged in a lateral line on body.

  • A ghost flatheads, Hoplichthys langsdorfii Cuvier and Valenciennes of the family Hoplichthyidae was studied for the first time in Korea. Eighteen specimens were collected from Pusan in February 3, 1993. The Haplichthys langsdorfii is similar to H. gilberti in morphometric characters, but H. langsdorfii differs from H. gilberti in having 2 rows of spinous processes on the scute of both side of body and longer snout than eye diameter. A new Korean name "Gasiyangtae" is proposed for the H. langsdorfii.

  • The synaphobranchid eel, Dysomma anguillare was redescribed on the basis of a specimen collected from the Yellow Sea, Chollabuk-do, Korea. The D. anguillare was characterized by many fleshy plicae at the front of upper and lower jaws, dorsal fin originated in slight advance than pectoral fin base, degenerated eyes, very short trunk and long tail, anus located below near tip of pectoral fin and no scales.

  • External morphology of three species of damselfishes, Chromis notata, C. analis and C. fumea were studied based on the samples collected from the Korean waters from 1993 to 1994. In morphology of the black spot at base of pectoral fins, C. notata has a large triangluar spot at Cheju population and a small circular spot at Sin - am. In the length of pelvic fin, C. notata of Korea can be classified into 3 groups. First group has a pelvic fin that extends to the origin of anal fin, second extends to the anus, third not extend to the anus. C. analis has higher body depth than C. notata and C. fumea in % of standard length. C. fumea has a minute serrate preopercle and no black spot at base of pectoral fins. In distribution, C. notata has a more widly distriubtion area than C. analis and C. fumea. Therefore, C. notata has more tolerance of cold waters than C. analis and C. fumea.

  • The taxonomic revision of the genus Periophthalmus from Korea was made based on the fish specimens collected in the southern and western coasts of Korea from September 1983 to October 1994. The genus Periophthalmus in Korea was classified into two species : P. modestus and P. magnuspinnatus n. sp. P. magnuspinnatus differs from all other species of the genus by ventral fin united about two - third the fin and first dorsal fin relatively large, convex, distinct black submarginal band.

  • Two specimens of the carangid fish Decapterus akaadsi Abe were collected for the first time in Busan, Korea. It is differentiated from the other three species of Decapterus by the number of rays in the dorsal and anal fins, gill rakers, scutes, and extent of predorsal scale. These specimens represent the first record of Decapterus akaadsi from Korea. A new Korean name 'Bulkeon karagi' is proposed for this species.
